REVERSIBLE WINDOW BRACKET.

Application filed August 6, 1927. Serial No. 211,073.

This invention relates to an improvement in brackets for supporting and controlling the movements of reversible casement window sashes.

The object of the invention is to provide a sash mounting or bracket in which the parts are of simple construction. Application of the bracket requires neither special tools not usually found in the ordinary household, nor special skill, and in which continued easy operation is assured.

A further object is to eliminate the difficulties encountered in use of articles of this type heretofore in use, chief among which is the readiness with which deterioration takes place in exposed portions of the sash mounting, thereby rendering operation of the sash 'diflicult.

A further object is the provision of a mounting in which the bearing surface is completely shielded in such way that foreign materials such as grit cannot enter between the sliding surfaces, and in which ice and snow are prevented from entering. The bearing surface being comparatively small, the sliding friction is reduced to a minimum.

Other objects and advantages will appear from time to time in the following description.

In the accompanying drawings forming a part of this specification, a simple preferred embodiment of the invention is shown. In the drawings, like reference numerals refer to like parts, and more particularly, in the drawings,

Fig. 1 shows a top plan view of the entire arrangment.

Fig. 2 shows a vertical section taken on the line 22 of Fig. 1; and

Fig. 3 shows a vertical section of the modification required for the mounting of a woodcn sash.

Reference numeral 1 indicates a channel member which is adapted to be fastened to the usual window sill by bolts or screws pass ing through holes 2 formed in the channel member 1. An inwardly projecting lip 3 is formed upon the channel member 1 by bending one side of the channel first inwardly at right angles, then parallel to the normal direction of the channel. On the reentrant sun face formed, a sliding member 4 is fitted which is adapted to slide along the length of the channel member 1. Due to the structure of the cooperating channel and sliding member, an extremely small protected bearing surface 9 is provided; hence the sliding friction is decreased very materially over the devices shown by the prior art. The bearing 9 being protected or inclosed also prevents foreign matter from entering the space between the channel and the sliding member. It provides protection from the elements and prevents clogging due to the accumulations of extraneous materials. Pivoted upon the slide 4, as at 6, is a window supporting member 5 which is in turn supported by connecting member 7 pivoted near the ends of both the member 5 and the channel 1. Holes 8 are provided within the window supporting member 5 to permit adjustment of the device to sashes of various sizes and the adjustment of the same window sashes to various positions.

In use, the invention is applied to the frame of an ordinary casement window, the guide member being fastened to the usual window sill and a similar member being fastened to the corresponding top member of the window frame. The casement window with its vertical pivots is set into the desired holes provided for the pivots in the sash supporting arm. It will be seen that when the sash is supported in this position, it may be reversed or by moving the sliding member the sash supporting arm and its attendant connecting link will be moved horizontally toward the side of the window frame, swinging the window sash about its vertical pivot and carrying the sash into a close parallel relation with the window frame.

Having thus described the invention by way of illustration, it should be understood that modifications within the scope of the appended claims may be made without departing from the spirit of the invention, and what I claim as new and desire to secure by Letters Patent of the United States is:

1. In a casement window mounting, a guide member adapted to be fixed to the window frame and having a horizontal outwardly extending portion, a portion extending downwardly from the horizontal portion, and an inwardly extending flange formed on the lower edge of the downwardly extending portion and spaced from the horizontal portion toform a guideway, a member sliding in said guide member, a window sash supporting member pivoted to said sliding memher, and a connecting member pivotally connected to said sash supporting member and said guide member.

3. In a casement window mounting, a guide member formed from a channel bar having one side bent back upon itself to provide a bearing surface parallel to the sides of said channel and located at substantially the central point between the sides of the channel bar, a sliding men'iher being grooved to fit into said channel, a sash supporting arm pivotally fastened to said sliding member, and aeonneeting arm pivotally fastened to said sash supporting arm and said guide member. 25

In testimony whereof I affix my signature.
